고속용 강체전차선 이행장치가 개시된다. 본 발명에 따른 고속용 강체전차선 이행장치에 의하면, 전기철도의 고속화 추세에 대응하여 이행장치의 구조적 안정성을 향상시킬 수 있고, 현수전차선과 강체전차선의 강성 또는 탄성을 점진적으로 변화시킴으로써 전차선에 가해지는 응력을 완화시키는 역할을 하여 열차의 속도를 최대한 유지시킬 수 있다. 그리고 이행장치의 강성이나 탄성 변화율이 작게 하고, 설치시 처짐량이 작도록 구현할 수 있으며, 열차의 통과주파수(Passing Frequency)와 이행장치의 공진주파수를 서로 절연시켜 분리 마진을 높일 수 있다. 또한, 전차선에 대한 그립력을 높이고 이행장치의 어느 부분이나 지지가 가능하도록 하여 시공자유도를 향상시킬 수 있다.

    Disclosed is a high-speed trolley bar transition device. The present invention relates to a high-speed trolley bar transition device capable of improving structural stability of the transition device in response to a high-speed trend of an electric railroad; gradually changing rigidity or elasticity of a catenary bar and a trolley bar; and maximally maintaining the speed of a train by mitigating stress applied to the catenary bar and the trolley bar. The present invention reduces the rigidity or an elastic change rate of the transition device; reduces an amount of deflection during installation; and increases a separation margin by isolating a passing frequency of the train and a resonance frequency of the transition device. The present invention increases grip force for the bar, and improves operator inducement by supporting any part of the transition device. The high-speed trolley bar transition device comprises a plurality of hollow units.
